BASE OF COOK-STOVES.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed August 23. 1907! Serial No. 390,562x

0 all whom it may concern:

Be it known that I, ALICE DAnRow, citizen of the United States, residingat Simpson, in the county of Mitchell and State of Kansas, have inventedcertain new and useful Improvements in Bases of Cook-Stoves, of whichthe following is a specification.

This invention has for its object a simple, durable and efficientconstruction of stove casters arranged in the base of a stove and soconstructed that the casters may be held from turning in order to holdthe stove in a perfectly rigid or stable condition on the lioor, andcapable of being easily released from locked position, so that the stovemay be moved along the floor whenever desired.

WVith this and other objects in view, as will more fully appear as thedescription proceeds, the invention consists in certain constructions,arrangements and conditions of the parts that I shall hereinafter fullydescribe and claim.

For a full understanding of the invention, reference is to be had to thefollowing de scription and accompanying drawings, in which:

Figure 1 is a perspective view of my invention. Fig. 2 is a detailtransverse section of one of the legs. Fig. 3 is a similarview at rightangles to Fig. 2. Fig. 4 is a vertical section taken through the base,showing the casters in unlocked position.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawings, the numeral 1 designates the base of a stoveequipped with the improved casters of my invention, said base embodyingtwo sides 2 and ends 3. At the corners of the frame-like base 1 are thebifurcated legs 4, which project downwardly from the base and in whichare journaled roller casters 5, mounted upon the shafts or spindles 6.Each caster 5 is formed in its periphery with a circumferentiallyextending series of notches 7, into any one of which a locking pin 8 isdesigned to enter, whereby to hold the casters from rotation. The pin 8projects downwardly through the cross bar 9 secured within the lowerends of the legs 4, and is carried by and projects downwardly from theblock or head 10 formed on the lower end of a vertically extending stem11. A coil spring 12 encircles each stem 11 and bears against the head10 and against an upper cross bar 13, so as to have a tendency to movethe stem and head downwardly in a direction to cause the pin 8 to enterthe notches 7.

In orderto retract the pins 8 from the notches of the roller casters '5,a fork 14 is fulcrumed intermediate of its ends on the upper end of therespective stems 11, the members of the fork embracing a preferablystationary collar or the like formed on the stem, and the ends of saidforks are adapted to bear upon the upper surfaces of the respectiveupper cross bars 13, so that when the rear ends of the forks are pulledupwardly, they will cause the upward movement of the stem to take place.

Opposite forks 14 are connected together for simultaneous actuation bymeans of the link rods 15, said rods being connected together at theiradjoining ends and operatively attached to front and rear operatinglevers 16 that are notched, as shown, and that are adapted to extendoutwardly through slots 17 formed in thefront and rear sides of the base1.

From the foregoing description in connec tion with the accompanyingdrawings, the operation of my improved locking caster will be obvious.Vhenever the operating levers 16 are pulled upwardly or rocked in thebottoms of the slots 17 in a direction to pull upwardly upon the linkrods 15, it is manifest that the forks 14 will be rocked and cause thestems 11 to move upwardly so as to disengage the locking pins 8 from theroller casters 5'.

Having thus described the invention, what is claimed as new is: j

1. A stove base, legs projecting downwardly from said base and securedthereto, roller casters journaled in the lower ends of said legs andprovided with notched peripheries, locking pins adapted to enter thenotches of said casters, stems having a vertical movement in therespective legs and carrying said pins, said-stems being spring pressed.downwardly, and means for moving said stems upwardly so as to carry thepins out of engagement with the casters.

2. A stove base, bifurcated legs secured thereto and projecting belowthe base, roller casters ournaled in the lower ends of said legs andprovided in their peripheries with notches, cross bars secured withinthe respective legs above the casters, stems mounted to move verticallywithin the legs the same stationary, means for raising the stems out ofengagement with the casters, 15 link rods connected to the raising meansof opposite stems, and operating levers operatively connected to theadjoining ends of the link. rods.

In testimony whereof I afliX my signature 20 in presence of twowitnesses.
